USB

Pigeon RB350 has two USB host ports. The total current of all USB +5V outputs and the +5V DC connector output should not exceed 1A. More details about power control can be found in the Power control section.

GPIO6 is connected to the RESET signal of the USB hub and the Ethernet controller (LAN9514 chip). The RESET input assertion time (low state) must be at least 1 μs.

The fourth USB port, marked as "USB DEVICE," should be used only for system updates.
